A Buchan trap (alternative names: Bristol interceptor,[1]interceptor trap and disconnecting trap) is a device fitted in a domestic sewer pipe to prevent odours entering the pipe from the public sewer[2] and permeating the house, a common problem before individual plumbing fittings were separately trapped. The trap is made from fireclay[1] and uses a water seal to prevent air passing from the sewer to the pipe. Waste flows from the house through a U-bend in the trap. This means that there is always water in the pipe preventing the passage of anything from the other direction. The device is a large clay U-bend with an air-inlet/access point on the 'house' side. It is located below the ground level, but can be accessed through the air-inlet and sometimes a rodding hole.[2]
